MICHAEL JOSEPH STEIN, OF NEW YORK, N. Y.

Specification forming part of Letters Patent No. 85,486, dated December29 18158.

To all whom it may concern Be it known that I, hIIGHAELJQSEPII STEIN, ofthe city, county, and State of New York, have invented a new and usefulImprovement ini.-Machines for Channeling Soles of Boots and Shoes, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawing, forming part of thisspecification, and in which- Figure 1 represents a partly-sectionallongitudinal elevation for a sole-channeling machine embracingmyimprovements; Fig.2, a transverse section, taken mainly as indicatedby'the line war in Fig. 1; and Fig. 3, a plan of the same, showing aportion in section, gakeii mainly as denoted .by the line z z in Similarletters of reference indicate corresponding parts.

(.lhanneling-machines have heretofore been constructed to cut thegrooves or channels on the grain side of the sole, so as. to enable themanufacturer in putting on the sole to improve the finish of his work bycovering up the nails, pegs, screws, or,'it"may be, stitchas by acertain description of machine,the stitchcsare run through and through.Such machines are unsuitable for channeling the soles of turned shoes,an entirely different class of worlqfor'which my improved machine isspecially adapted. This class of work requires the channel or channelsto be cut on the flesh instead of on the grain side of the leather, andto be so done as not to break or mar the grain, which is the finishingside of the-sole. Roughened vertical feeding-rollers,-

therefore, acting on opposite sides of the sole, as heretoihre used, areunsuitable for the purpose, inasmuch as they break or mar the grain, andare-generally defective in failing to draw up the sole against the guidein advance of or at the out, and by reason of the small extent ofbearing-surface the lower roller presents for the sole torest upon, androughened character of its edge, also'as the leather varies in consistency or firmness, cause the channels to be cut of irregular depth. Theseand other difiiculties are obviated by my machine, and certain otherspecial advantages obtained.

My invention consists, first, in a combination, with channeling knivesor cutters and with a guide to direct :the edge of the sole, of an upperroughened feed 'roller or Wheel and a'lowcr smooth, or nearly smooth,revolving table, located at right angles, or thereabout, to the upperfeed-roller, whereby the objections hereinbefore referred to :areobviated.

Second, my invention consists in a combination, with thechanneling-knives, upper feed roller, and lower revolving table, of aguiderollcr arranged to bear on the "sole immediatel y in advance of theknives, or thereabout, for the double purpose of guiding and keeping thesole down on the table and of preventin g the roughened periphery of theupper feedroller from sinking too deep or irregularly into the leather.

Third, the invention consists in a combination of mechanism ordeviceswith the guide which directs the edge of the sole relatively tothe knives, in such manner as that while the machine is running saidguide ma be gradually adjusted to and from the knives, to increase thedistance of the channels from the edge of the sole at the shank andheel, or either, for the purpose of facilitating paring of the sole atthose parts without cutting the stitches, and toprovide forintroduction'of the counter or stiffening at the heel.

Referring to the accompanying drawing, A

represents a main or driving shaft, carrying a pinion, a, which gearswith a spur-wheel, l5, on a shaft, B, that carries on its front end abevel-pinion, c, which gives revolving motion to a horizontal table, O.

Arranged at right angles to this table, over the back edge of it, is anupper feed roller or wheel, 1), formed with projections, or of aroughened character, on its periphery, and set in motion or rotated byor through a wheel, d, on its shaft, arranged to go. -withtliespnrwheel:7). Said feed-roller shaft, also channelin g-knives, guide or guidesand pertaining devices, as hereinafter descri ed, are all'hung to orconnected with an. upper frame or arm, E, hinged, as at c, and held downby a spring,

j, acting on an extension of a connectingstrap, 9, but capable of beingraised by atreadlc or lever, h, when necessary to introduce and takeoutthe sole to and from the machine. F is the inner channeling-lcniic,and Gths; outer channeling-cutter, adjustable relatively upper feedwheel, of a guide and pressing roller arranged to work in closeproximity to the feed-wheel andrelatively to the knife or knives,essentially as herein set forth;

3. In combination with the channelingknifeor knives, the guide H, madeadjustable by mechanism under the control of the operator to graduallyvary the distance of the channel or channels from the edge of the solewhile the machine is running and. the sole being fed across or throughit, substantially as specified.
